Description

Follow-on cement package bags

Technical field

The utility model is related to a kind of packaging bag, refers in particular to a kind of follow-on cement package bags.

Background technology

Cement package bags are the sacks for containing cement, and transport of cement can be made more to facilitate, and easily carry and store. In filling cement, when toward filling cement in packaging bag, and the gas part in bag of cement cannot discharge, and some positions do not fill It is real, the weight of influence cement pack, it is sometimes necessary to packaging bag is shaken and discharges gas, refill some cement, it is ensured that be every One bag of cement weight is consistent, and pack has some setbacks；And in stacking, if there is gas in bag, whole bag cement will be in stacking Pressure increases and quick-fried bag occurs in process stress bag；And, present cement package bags are mostly the bags of rectangle, do not have any confession The handle that carrying is used, in workers carry's bag of cement, can only be lifted or be shouldered using hand, and the work for having aggravated porter is difficult Degree.

In view of this, the design people is directed to not attaining in above-mentioned cement package bags structure design and improves caused many missings And inconvenience, and deeply conceive, and actively research improvement has a fling at and develops and design this case.

Utility model content

The purpose of this utility model is to provide a kind of follow-on cement package bags, can in filling cement smooth dress Bag；Can be also vented automatically when being stacked after packaging, it is to avoid have the gas that cannot discharge in bag and in stacking process stress bag Interior pressure increases and quick-fried bag occurs；And air permeable belt can be convenient to carry in handling process as handle.

In order to reach above-mentioned purpose, solution of the present utility model is：

A kind of follow-on cement package bags, it includes marsupial body, the bag body have sealable upper shed and Under shed, the upper shed is used for filling cement, and the two ends extension of the under shed is connected with air permeable belt, and the air permeable belt has The gas-permeable channels connected with bag body, the air permeable belt has the seal end of sealing gas-permeable channels.

The air permeable belt has outer layer air-permeable layer, middle membrane layer and internal layer air-permeable layer, and the outer layer air-permeable layer distribution is more Individual first air-vent, the internal layer air-permeable layer is distributed multiple second air-vents.

First air-vent, the second air-vent are shifted to install.

The air permeable belt and bag body intersection are provided with breathable films.

The air permeable belt and bag body intersection are provided with one-way exhaust valve.

After said structure, the utility model cement package bags in filling cement, upper shed of the cement from bag body Pour into, the intrinsic gas of bag is discharged from the air permeable belt under shed two ends, can be tried one's best and be discharged gas in bag, it is ensured that cement is packed It is smooth；Can be also vented automatically when being stacked after packaging, it is to avoid have the gas that cannot discharge in bag and in stacking process stress Pressure increases and quick-fried bag occurs in bag；And air permeable belt can make carrying personnel reduce work in handling process as handle Bear, it is convenient to carry.

Specific embodiment

In order to the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment Row is elaborated.

Fig. 1 and Fig. 2 is referred to, the utility model discloses a kind of follow-on cement package bags, and it includes marsupial body 1, the bag body 1 have sealable upper shed 11 and under shed 12, the upper shed 11 be used for filling cement, it is described under open The two ends extension of mouth 12 is connected with air permeable belt 13, and the air permeable belt 13 has the gas-permeable channels 14 connected with bag body 1, described Gas is with 13 seal ends 15 with sealing gas-permeable channels 14.

In filling cement, cement is poured into the utility model cement package bags from the upper shed 11 of bag body 1, bag body 1 Interior gas is discharged from the air permeable belt 13 at the two ends of under shed 12, can be tried one's best and be discharged gas in bag, it is ensured that cement pack is smooth； Can be also vented automatically when being stacked after encapsulation, it is to avoid have the gas that cannot discharge in bag and in stacking process stress bag pressure Increase and quick-fried bag occurs；And air permeable belt 13 can make carrying personnel reduce work load in handling process as handle, It is convenient to carry；When cement is poured out, can be ventilated to air permeable belt 13 when being finished down, the cement remained in bag can be blown Go out, it is to avoid cause to waste in cement delay bag.

The air permeable belt 13 of the present utility model has outer layer air-permeable layer 131, middle membrane layer 132 and internal layer air-permeable layer 133, the outer layer air-permeable layer 131 is distributed multiple first air-vents 134, and the internal layer air-permeable layer 133 is distributed multiple second and breathes freely Hole 135；Air permeable belt 13 is provided with multiple first air-vents 134, the second air-vent 135, can facilitate and discharge the gas in bag, And middle membrane layer 132 can prevent cement from letting out, it is to avoid cement is leaked, environment is polluted.

First air-vent 134 of the present utility model, the second air-vent 135 are shifted to install, and air permeable effect is more preferably.

The air permeable belt 13 of the present utility model and the intersection of bag body 1 are provided with breathable films 16 or one-way exhaust valve； Can try one's best and gas is discharged by air permeable belt 13, and cement does not enter air permeable belt 13 and will not be leaked out by air permeable belt 13, keeps away Exempt from cement leakage, pollute environment.

The two ends of the under shed 12 of the bag body 1 of the present utility model form circular arc type bag angle, when cement is poured out, can Avoid cement from being detained in the bag angle of perpendicular type, reduce the residual of cement.

Above-described embodiment and accompanying drawing and non-limiting product form of the present utility model and style, any art Appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
